Yes, it is true. Any circles with the same radius will have the same circumference as well.
The center of a circle is the same for all circles but the length of the radius can change
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi
They are congruent or identical circles
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.

Circles with the same radius are congruent circles.

2 circles can be congruent. The have to have the same radius.
congruent circles
The same radius.
No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
congruent
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
They are congruent or identical circles
They are said to be concentric circles.
